2813692cc2 Merge common XPT_CALC_GEOMETRY functions into a single convenience function. 
Devices below may experience a change in geometry.

* Due to a bug, aic(4) never used extended geometry.  Changes all drives
  >1G to now use extended translation.
* sbp(4) drives exactly 1 GB in size now no longer use extended geometry.
* umass(4) drives exactly 1 GB in size now no longer use extended geometry.

For all other controllers in this commit, this should be a no-op.

7e71df9339 Bring back bus_dmasync_op_t. It is now a typedef to an int, though the 
BUS_DMASYNC_ definitions remain as before.  The does not change the ABI,
and reverts the API to be a bit more compatible and flexible.  This has
survived a full 'make universe'.

7a648f56cf I deserve a big pointy hat for having missed all those references 
to bus_dmasync_op_t in my last commit.

2c6a3591f9 Convert the use of vtophys() for doing autosense to use busdma. Also correct 
some error codes that get returned to CAM.

ed34d0ade2 Turn on interrupt-entropy harvesting for all/any mass storage devices 
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

e39756439c Back out the previous change to the queue(3) interface. 
It was not discussed and should probably not happen.

740a1973a6 Change the way that the queue(3) structures are declared; don't assume that 
the type argument to *_HEAD and *_ENTRY is a struct.

by 924 bytes.

76fbc068b8 Per conversations in -current, add #error to these drivers when you don't 
have the right compatibility shims enabled.  ISA drivers to follow later.

086646f7c6 Properly set the alignment argument to bus_dma_tag_create(). If we 
don't care about the alignment, set it to 1, meaning single byte alignment.

1723e869c1 First cut at a driver for the amd53c974 PCI SCSI host adapter. This 
driver lacks error recovery and still needs more testing, but it's
about time I got it under revision control.
